First of all, i really love your game, but i've been experience a few "bugs" lately.

Today my Archers lost a skill upgrade "View and Range" i cannot give them a longer range anymore???

Second today i tried to siege Pultrak twice... but when i get inside their innerwall, my game crashes and says "DOF" is responding anymore... i really hope you can fix this for me, since i lose a few units and have to go all the way back to my elf base to get new units.

Suggestion: could you do so when i Ctrl Group one of my units it stays saved? instead of i have to make new Ctrl Group everytime a new battle starts.
